Abstract

Microstructured polymer optical fibers represent quite new technology that is still in the research and development stage. However, some advances and possible applications are available even now. One of these is the possibility of filling the fibers with various fluids to enhance or modify some of their characteristics. Filling fibers with fluorescent dyes is a good method to describe how the filled fiber behaves and to demonstrate sensing applications.

Emission obtained from fluorescent dye-filled samples at peak wavelengths; all the samples had lengths of 0.5 m. We used the data from a sample filled with a blank solution (10% alcohol in water) to determine the fluorescence.
